AME 113 NL / NLX

AME 113 is a series of gear actuators for opening and closing valves for heating and cooling systems. The predominant application is energy-efficient control of water-bearing valves in building services and automation. The actuator has a safety function: if the power supply fails, the valve pressure plate moves to a parking position using energy from an internal rechargeable accumulator. The actuator has an equal percentage characteristic, meaning the flow through the valve is proportional to the control signal. Control is performed by a 0-10 V DC signal sent by a central DDC system or a room thermostat. The current position and control voltage are shown on an LC display. The actuator comes with a pluggable connecting cable and has a manual valve adjustment for maintenance or installation. A version with feedback signal is available, transmitting information about the current valve position and any occurred errors to the DDC installation.
